Description

Technical Field

[0001] This invention relates to the field of ocean current power generation equipment technology, and in particular to a directional automatic speed-regulating ocean current power generation device. Background Technology

[0002] With global economic development and increased human activity, energy demand is constantly rising, while environmental problems are becoming increasingly serious. Traditional fossil fuels not only have limited reserves, but their utilization also generates large amounts of greenhouse gases and other pollutants, exacerbating global climate change and environmental pollution. Therefore, developing and utilizing renewable energy sources, such as ocean current energy, has become an important way to solve the energy crisis and environmental problems. Ocean current energy is a clean and sustainable energy source with enormous development potential. However, the utilization of ocean current energy faces technological challenges, such as low energy density and low conversion efficiency.

[0003] Existing ocean current power generation technologies mainly include subsea turbine generator sets and floating trolley generators. Subsea turbine generator sets are highly efficient when ocean currents are stable, but they are poorly adaptable to changes in ocean current direction and velocity, lack an effective automatic speed regulation mechanism, and are prone to equipment damage or efficiency reduction. Floating trolley generators rely on the undulating motion of ocean currents or waves, so their power generation efficiency is easily affected by changes in current velocity and waves, and there is also a risk of equipment damage under high current velocities. The shortcomings of existing technologies limit the stability, efficiency, and adaptability of ocean current power generation equipment.

[0004] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, this invention discloses a directional automatic speed-regulating ocean current power generation device, comprising a power module 100, an automatic speed-regulating module 200, a power generation module 300, and a protection module 400. The power module 100 faces the ocean current and converts either forward or reverse currents into power output in the same direction. The automatic speed-regulating module 200 adaptively adjusts the output power speed according to the power module's output speed. The power generation module 300 converts the speed-regulating power into electrical energy output. The protection module 400 is connected to the automatic speed-regulating module 200 and adaptively protects the power module 100 according to the ocean current speed.

[0029] like Figure 2 and Figure 3As shown, the power module 100 includes a left turbine 101, a one-way bearing 102, a left turbine coupling 103, a left synchronous pulley 104, a horizontal bevel gear 105, a vertical bevel gear 106, a drive shaft 107, a right turbine 108, a right turbine coupling 109, a flange 110, a sleeve 111, a bearing 112, a pawl 113, a ratchet 114, a right synchronous pulley 115, a synchronous belt 116, and a right synchronous pulley coupling 117. The left turbine 101 and right turbine 108 are two turbines with blades rotating in opposite directions. The sleeve 111 is a cylinder with a bearing hole at one end and four holes at the other end, the rest being solid. When the ocean current flows past the left turbine 101, the left turbine 101 rotates clockwise, and the left turbine coupling 103 connected to the left turbine 101 also rotates clockwise. One-way bearing 102 is connected to left turbine coupling 103 to ensure that power is transmitted in only one direction, preventing reverse rotation. Since the blades of right turbine 108 rotate in the opposite direction to those of left turbine 101, right turbine 108 rotates counterclockwise, causing right turbine coupling 109 connected to right turbine 108 to rotate counterclockwise. Flange 110 is fixed to right turbine coupling 109 and secured to the four holes of sleeve 111 with screws. When right turbine coupling 109 rotates counterclockwise, flange 110 connected to right turbine coupling 109 also rotates counterclockwise, causing sleeve 111 connected to flange 110 to rotate counterclockwise. Since pawl 113 is fixed to sleeve 111, pawl 113 rotates as sleeve 111 rotates counterclockwise. Left turbine coupling 103 is connected to left synchronous pulley 104, so that the clockwise rotation of left turbine coupling 103 drives left synchronous pulley 104 to rotate clockwise. The left synchronous pulley 104 drives the right synchronous pulley 115 to rotate via the synchronous belt 116, causing the right synchronous pulley coupling 117 connected to the right synchronous pulley 115 to rotate clockwise. This, in turn, causes the ratchet 114 fixed on the right synchronous pulley coupling 117 to rotate clockwise. The bearing 112 is fixed in the bearing hole of the sleeve 111 and is connected to the right synchronous pulley coupling 117. Counterclockwise rotation of the sleeve 111 causes the outer ring of the bearing 112 to rotate counterclockwise, while the inner ring connected to the right synchronous pulley coupling 117 rotates clockwise, and the two do not interfere with each other. At this time, the ratchet 114 and the pawl 113 slide relative to each other without causing any impact. Simultaneously, the rotation of the left synchronous pulley 104 drives the horizontal bevel gear 105 to rotate clockwise. The horizontal bevel gear 105 then transmits power to the drive shaft 107 connected to the vertical bevel gear 106 through meshing with it. The drive shaft 107 is fixed in the bearing housing, further transmitting power to the automatic speed control module 200. When the ocean current flows past the left turbine 101 from the opposite side, the one-way bearing 102 prevents the left turbine 101 from rotating in the opposite direction, while the right turbine 108 rotates clockwise due to the direction of the ocean current. The right turbine coupling 109 connected to the right turbine 108 also rotates clockwise, causing the sleeve 111 to rotate clockwise as well.At this time, the pawl 113 on the sleeve 111 engages with the ratchet 114, ensuring that the ratchet 114 rotates clockwise, thereby driving the right synchronous pulley coupling 117 connected to it to rotate clockwise, which in turn causes the right synchronous pulley 115 to rotate clockwise. The left synchronous pulley 104 rotates clockwise through the action of the synchronous belt 116. This design ensures that the speed transmitted to the automatic speed control module 200 remains in one direction regardless of whether the ocean current is forward or reverse.

[0030] like Figure 4As shown, the automatic speed control module 200 includes a flange bearing housing 201, a coupling 202, a base 203, a pull column 204, a connecting rod 205, a connecting shaft 206, a disc 207, a slider 208, a spring 209, a disc bearing 210, a lower fixed block 211, a frustum 212, a helical bevel gear 213, an upper horizontal bevel gear 214, a helical shaft 215, and an upper fixed block 216. The flange bearing housing 201 is connected to the drive shaft 107 in the power module, and the portion of the drive shaft 107 extending out of the flange is connected and fixed to the lower end of the coupling 202. The upper end of the coupling 202 is connected and fixed to the round shaft at the lower end of the base 203 of the centrifugal mechanism. The centrifugal mechanism includes a base 203 with an extended shaft, a pull column 204, a connecting rod 205, a connecting shaft 206, a disc 207, a slider 208, and a spring 209. The slider 208 is fitted onto the extended shaft of the base 203. The bottom of the pull column 204 is fixed in the opening slot of the base 203 via an intermediate shaft, and the upper part of the pull column 204 is fixed to the upper ends of its two connecting rods 205 by bolts. Each connecting rod is connected and fixed to the extended part of the slider 208. The upper surface of the slider has three connecting shafts 206 connected to the disc 207. The disc 207 has a bearing hole in the middle, and the disc bearing 210 is installed in the bearing hole. The spring 209 is fixed to the uppermost end of the extended shaft of the base 203 to reset the slider 208. The lower fixing block 211 and the upper fixing block 216 are used to fix the frustum 212 and the inclined shaft 215. The frustum 212 is inverted and fits against the disc 207, and the generatrix of the frustum 212 is perpendicular to the ground. An inclined shaft 215 runs through the middle of the frustum 212, and the inclined shaft 215 rotates with the frustum 212. A helical bevel gear 213 is fixed to the upper end of the slanted shaft 215, while another upper horizontal bevel gear 214 is fixed to another central shaft and meshes with the helical bevel gear 213, effectively transmitting power to the power generation module. When the power module transmits power upwards, the centrifugal mechanism begins to rotate, and the disc 207 rotates accordingly, causing the frustum 212 it is in contact with to rotate. This causes the meshing bevel gear 213 and the upper horizontal bevel gear 214 to rotate, transmitting power to the power generation module. At slower speeds, the disc 207 rotates in contact with the bottom of the frustum 212. Because the bottom radius of the frustum 212 is small, it can obtain a large angular velocity, amplifying the speed. As the speed gradually increases, the centrifugal force causes the pull column 204 to pull outwards, and the connecting rod 205 drives the slider 208 to move upwards. At this time, the disc 207 adheres upwards along the generatrix of the frustum 212. Because the upper part of the frustum 212 has a large radius, the obtained angular velocity is relatively small, achieving speed reduction and ensuring that the speed transmitted to the power generation module is appropriate. As slider 208 moves upward, it compresses spring 209. As the speed gradually decreases, spring 209 returns to its original length, pushing slider 208 back to its initial position, thus completing the automatic reset.

[0031] like Figure 5As shown, the power generation module 300 includes a pinion 301, a pinion shaft 302, a large gear shaft 303, a large gear 304, a large gear shaft bevel gear 305, a lower bevel gear 306, a lower bevel gear shaft 307, a coil 308, a magnet connecting plate 309, a magnet 310, and a coil fixing platform 311. The pinion shaft 302 is fixed to the upper horizontal bevel gear 214 in the automatic speed control module 200. The rotation of the upper horizontal bevel gear 214 will drive the pinion shaft 302 to rotate, thereby transmitting the power of the automatic speed control module 200 to the power generation module 300. The pinion 301 is fixed on the pinion shaft 302, and the rotation of the pinion shaft 302 will drive the pinion 301 to rotate. The rotation of the pinion 301 will transmit power to the large gear 304 meshing with it. The large gear 304 is fixed to the large gear shaft 303, and the rotation of the large gear 304 will drive the large gear shaft 303 to rotate. Since the large gear shaft bevel gear 305 is fixed to the large gear shaft 303, the large gear shaft 303 will drive the large gear shaft bevel gear 305 to rotate together. The large gear shaft bevel gear 305 meshes with the lower bevel gear 306, causing the lower bevel gear 306 to rotate. The lower bevel gear 306 is fixed to the lower bevel gear shaft 307, and the rotation of the lower bevel gear 306 will cause the lower bevel gear shaft 307 to rotate. The flange is fixed together with the magnet connecting plate 309 and fixed to the lower bevel gear shaft 307. The magnet connecting plate 309 is connected to the magnet 310 on both sides by bolts and nuts, ensuring that the magnet 310 is fixed to both sides of the magnet connecting plate 309. There are four coils 308, fixed to the coil fixing platform 311. The coil fixing platform 311 is fixed to the lower bevel gear shaft 307 by bearing seats, ensuring that it does not rotate with the lower bevel gear shaft 307 but remains stationary. When the bevel gear shaft 307 rotates, it drives the magnet connecting plate 309 to rotate, and the magnet 310 rotates, and the coil cuts the magnetic field lines to generate electricity.

[0032] like Figure 6As shown, the protection module 400 includes a push column 401, a fixed connecting rod 402, a flange connecting plate 403, a flange connecting shaft 404, a rotating connecting rod 405, a protection box rod 406, a box rod slot 407, a snap fastener 408, and a protection box 409. The push column 401 is fixed in the disc bearing 210 on the disc 207 in the automatic speed control module 200, ensuring that the push column 401 does not rotate with the rotation of the disc 207. There are four fixed connecting rods 402, two at each end. The upper part is fixed to one end of the rotating connecting rod 405 by bolts, and the lower part is fixed to the push column 401 by bolts. The upper part of the other end of the rotating connecting rod 405 is also connected to the two fixed connecting rods 402 by bolts, and the lower parts of these two fixed connecting rods are connected to the protection box rod 406 by bolts. The middle of the rotating connecting rod 405 is connected to two flange connecting plates 403, one on each side, and fixed to the flange connecting shaft 404. The function of the rotating connecting rod 405 is to convert the linear motion of the pusher 401 into rotational motion, and through its cooperation with the fixed connecting rod 402, ensure that the rotating connecting rod 405 can rotate gradually during the upward movement of the pusher 401. When the pusher 401 rises, the rotating connecting rod 405 rotates counterclockwise, thereby driving the protective box rod 406 downward. The protective box 409 is engaged in the slot on the right side baffle via the snap fastener 408, and the protective box rod 406 is engaged in the protruding box rod slot 407 on the right side baffle to control the up and down movement of the protective box. As the ocean current speed increases, the pusher 401 gradually rises, and the rotating connecting rod 405 drives the protective box 409 to gradually descend. Finally, when the protective box 409 moves to a certain position, it will block the turbine and block the ocean current, thereby stopping the turbine's rotation and achieving the purpose of protecting the turbine. When the speed gradually decreases, the pusher 401 gradually descends, and the protective box 409 rises, restoring the turbine's normal operation, thus playing the role of protecting the turbine.
